This paper investigates a comparative study which addresses the P/prec/Cmax scheduling problem, a notable NP-hard benchmark. MLP_SACS, a modified ant colony algorithm, is used to solve it. Its application provides us a better job allocation to machin

The analysis of a preemptive priority queuing system with K(≥ 2) classes of jobs is undertaken. The system consists of a single processor representing a model of discrete dynamic scheduling problems associated with Mk/Gk/1/∞ endogenous priority q

We consider a scheduling rule called MBPS, the mean bounded priority scheduling, which prioritizes jobs by an index computed for each job as a weighed sum of the proportion of time it has been processed and the proportion of time it has been waiting

We show that a particular dynamic priority given to jobs in a multitasks operating system of computers is a deteriorating jobs or a delaying jobs scheduling. Under some assumptions we also show that it is an index rule. To do this, we present the too
